            <p>event Object</p>
            <h4 class="topLine"><b>treeId</b><span>String</span></h4>

            <p>zTree unique identifier: <b class="highlight_red">treeId</b>, the id of the containing tree.</p>
            <h4 class="topLine"><b>treeNodes</b><span>Array(JSON)</span></h4>

            <p>A collection of the nodes which has been dragged</p>

            <p class="highlight_red">The treeNodes are the data of the nodes which be dragged, when move nodes.</p>

            <p class="highlight_red">The treeNodes are the clone data of the nodes which be dragged, when copy
                nodes.</p>
            <h4 class="topLine"><b>targetNode</b><span>JSON</span></h4>

            <p>JSON data object of the target node which treeNodes are drag-dropped.</p>

            <p class="highlight_red">If the treeNodes will be root node, the targetNode = null</p>
            <h4 class="topLine"><b>moveType</b><span>String</span></h4>

            <p>the relative position of move to the target node</p>

            <p class="highlight_red">"inner": will be child of targetNode</p>

            <p class="highlight_red">"prev": will be sibling node, and be in front of targetNode</p>

            <p class="highlight_red">"next": will be sibling node, and be behind targetNode</p>

            <p class="highlight_red">If moveType is null, means drag & drop is cancel.</p>
            <h4 class="topLine"><b>isCopy</b><span>Boolean</span></h4>

            <p>the flag used to judge copy node or move node</p>

            <p class="highlight_red">true: copy node; false: move node</p>
